Up Helly Aa festival

(Source: the Internet)

This is a picture of the Up Helly-Aa festival which has been celebrated on the Shetland islands (North of Scotland) for over 100 years. They claim it to be the largest fire festival in Europe! (Have they heard of 'Falles' in Valencia?).
It is a fire festival of unknown origin to celebrate the end of the Yule season. Up to a thousand guizers march in procession holding torches which they later throw into a replica Viking ship and set it on fire.
